I have got this working on server 2012 R2 after having the issue running the bat file – cant find certmgr.exe I opened the bat file and run each step manually. Following the below steps should work for you :-

Ps if this doesn’t work open an elevated command prompt (right click on command prompt) cd (change directory) to the certificate folder and run the commands again (this is what I did – but the steps about seemed easier and should also work) – good luck!

That should be it 😀 Hope that helps someone and thanks for the original poster for making this possible! 😀

Very easy, and working! Thankssss!
Clue: First start CMD as Admin, THEN navigate to extracted folder and start the batch, this way it will work.
Starting the batch directly as Administrator didnt work for me at all.
